The article presents the results of the third mapping (2013) of the virgin steppe of the “Kuncherovskaya forest-steppe” – the protected area of the State Natural Reserve “Privolzskaya forest-steppe” (Penza region). The article describes the structure and dynamics of the steppe vegetation in the past 10 years. Steppe vegetation still prevails in the area, but meadow steppes become more mesophilic compared with the previous mapping. The authors point out a reduction of the association area, dominated by Helictotrichon desertorum (Less.) Nevski, due to an increasing participation of the associations with predominance of Stipa tirsa Steven. In addition, the area of meadow vegetation (steppefied meadows) has increased, especially on surfaces of the watershed of the protected area.
